 | [to](/src/cmd/to.rs#L2)<br>✨🚀 | Convert CSV files to [PostgreSQL](https://www.postgresql.org), [SQLite](https://www.sqlite.org/index.html), XLSX, [Parquet](https://parquet.apache.org) and [Data Package](https://datahub.io/docs/data-packages/tabular). |
 | [tojsonl](/src/cmd/tojsonl.rs#L3)<br>📇😣🚀 | Smartly converts CSV to a newline-delimited JSON ([JSONL](https://jsonlines.org/)/[NDJSON](http://ndjson.org/)). By scanning the CSV first, it "smartly" infers the appropriate JSON data type for each column. See `jsonl` command to convert JSONL to CSV. |
 | [transpose](/src/cmd/transpose.rs#L2)<br>🤯 | Transpose rows/columns of a CSV.  |
-| [validate](/src/cmd/validate.rs#L2)<br>📇🚀🌐 | Validate CSV data blazingly-fast using [JSON Schema Validation](https://json-schema.org/draft/2020-12/json-schema-validation.html) & put invalid records into a separate file with an accompanying detailed validation error report file (e.g. _up to 580,000 rows/second_ using [NYC's 311 schema](https://github.com/jqnatividad/qsv/blob/master/resources/test/311_Service_Requests_from_2010_to_Present-2022-03-04.csv.schema.json) generated by the `schema` command).<br>If no JSON schema file is provided, validates if a CSV conforms to the [RFC 4180 standard](#rfc-4180-csv-standard) and is UTF-8 encoded. |
